GRIMM "PTZD" Sneak Peek

The third season of GRIMM continues on Friday, November 1 at 9 p.m. ET/PT on NBC.

In "PTZD," Monroe (Silas Weir Mitchell), Hank (Russell Hornsby), Rosalee (Bree Turner) and Juliette (Bitsie Tulloch) track down a manic Nick (David Giuntoli) and do all they can to find him and reverse what’s been done to him before he causes any more damage.

Meanwhile, Captain Renard (Sasha Roiz) does his best to clean up the zombie fallout on all fronts – domestic and international.

Elsewhere, the more time Adalind (Claire Coffee) spends with Stefania (guest star Shohreh Aghdashloo), the more disturbing things seem to get in her quest to regain her Hexenbiest abilities.
